Cov hlau nplaum ruaj ruaj Brushless Tsav Magnet

Qee Qhov Taw Qhia ntawm Cov hlau nplaum tas mus li brushless lub cev muaj zog

Dab tsi yog Permanent Magnet brushless Tsav?

Brushless lub cev muaj zog yog ib yam khoom siv mechatronics, uas yog tsim los ntawm lub cev muaj zog thiab tsav tsheb. Txij li thaum brushless DC lub cev muaj zog ua haujlwm hauv hom kev tswj tus kheej, nws yuav tsis ntxiv qhov pib winding ntawm lub rotor zoo li lub tshuab synchronous pib nyob rau hauv hnyav load nyob rau hauv kev sib txawv zaus ceev tswj, los yog nws yuav tsis tsim oscillation thiab tawm ntawm kauj ruam thaum lub load hloov dheev. Cov hlau nplaum tas mus li ntawm me me thiab nruab nrab-qhov loj me brushless DC motors tam sim no feem ntau siv lub ntiaj teb tsis tshua muaj neodymium hlau boron (Nd-Fe-B) cov ntaub ntawv nrog qib siab sib nqus zog. Yog li ntawd, qhov ntim ntawm lub ntiaj teb tsis tshua muaj hlau nplaum brushless lub cev muaj zog yog ib tus lej me me dua li ntawm peb-theem asynchronous lub cev muaj zog nrog tib lub peev xwm.

Yuav tsum muaj brushless lub cev muaj zog rau hlau nplaum

Cov hlau nplaum tas mus li yog siv nyob rau hauv lub rotor ntawm brushless lub cev muaj zog, uas feem ntau yog neodymium hlau nplaum blocks thiab neodymium hlau nplaum vuas. Thestator yog ib qho excitation coil, tab sis cov qauv ntawm cov hlau nplaum ruaj khov sab hauv kuj txawv, uas feem ntau muab faib ua hom mount thiab hom embedded.

Qhov txawv yog:

Qhov saum npoo mount ncaj qha quadrature axis inductors Ld thiab Lq yog tib yam, nrog cov huab cua loj, me me sib nqus tsis muaj peev xwm thiab tsis muaj peev xwm nthuav dav.

Embedded AC-DC axis inductance: Lq >Ld, me me qhov sib txawv ntawm huab cua thiab zoo magnetic tsis muaj peev xwm.

Magnet kev ua tau zoo xav tau ntawm brushless lub cev muaj zog

Lub cev muaj zog brushless feem ntau yog siv high-performance tsawg lub ntiaj teb neodymium hlau nplaum, vim hais tias lub zog ntawm lub cev muaj zog yog ze ze rau kev ua tau zoo ntawm cov hlau nplaum. Nws tuaj yeem nkag siab tias qhov ntim thiab Qib ntawm neodymium hlau nplaum txiav txim siab lub zog siab tshaj plaws ntawm lub cev muaj zog.

Yuav tsum muaj cov hlau nplaum zoo li brushless lub cev muaj zog

Cov duab ntawm brushless lub cev muaj zog hlau nplaum feem ntau suav nrog Square hlau nplaum, Pobzeb (Arc) hlau nplaum, Nplhaib hlau nplaum thiab Bread magnet.

Qhov zoo ntawm Square hlau nplaum: kev ua haujlwm yooj yim thiab tus nqi pheej yig

Qhov zoo ntawm Pobzeb / Arc hlau nplaum: arc tuaj yeem xyuas kom meej tias huab cua sib txawv ntawm cov hlau nplaum thiab silicon steel ntawv zoo ib yam, thiab nws yog superior rau square hlau nplaum hauv lub zog thiab kev ua haujlwm.

Qhov zoo ntawm Bread shaped magnet: Raws li cov kws tshaj lij, lawv xav tias hom hlau nplaum no muaj txiaj ntsig zoo dua li arc hlau nplaum.

Qhov zoo ntawm Ring magnet: yooj yim installation, superior kev kawm, high-end feem ntau siv nplhaib.

Qhov yuav tsum tau muaj rau cov hlau nplaum ncej ntawm brushless lub cev muaj zog

Qhov tsawg tus ncej, qhov siab dua. Raws li pom hauv daim duab saum toj no.
